Paragraph 25.3
Of the Second London Baptist Confession of Faith
It is lawful for all sorts of people to marry, who are able with judgment to give their consent;1 yet it is the duty of Christians to marry in the Lord;2 and therefore such as profess the true religion, should not marry with infidels, or idolaters; neither should such as are godly, be unequally yoked, by marrying with such as are wicked in their life, or maintain damnable heresy.3
The Westminster Confession of Faith (1646)
24.3
It is lawful for all sorts of people to marry who are able with judgment to give their consent.1 Yet it is the duty of Christians to marry only in the Lord.2 And therefore, such as profess the true reformed religion should not marry with infidels, Papists, or other idolaters: neither should such as are godly be unequally yoked, by marrying with such as are notoriously wicked in their life, or maintain damnable heresies.3
